Proxy users, the proxy can be divided into three types: highly anonymous proxy, normal anonymous proxy, and transparent proxy.

(1) A high degree of an anonymous proxy does not change the client’s request, so the server looks like a real client browser to access it, then the customer’s real IP is hidden, the server does not think we are a proxy.

(2) The ordinary anonymous proxy can hide the real IP client but wants to change our request information, the server may think we use the proxy. However, the site may not be able to find your IP address, but you can still find your IP.

(3) Transparent agent, it only changed our request information, but also send a real IP address.

The three levels of hidden agent identity are most invisible to highly anonymous agents, followed by normal anonymous agent, and the worst is a transparent agent.

The proxy you find IP, is in your browser, it’s not difficult to Baidu Google,

If the site shows that there are two IP, then your proxy is transparent, the first IP is yours is original, and the second IP is your proxy IP.

Croydon is a South London town located in Charring Cross to the south 9.5 miles, it is one of Greater London’s 11 metropolitan centers.

Croydon has historically been part of Surrey County. During Norman’s conquest of England, Croydon had a church and a workshop, with about 365 inhabitants.

During the middle Ages, Croydon was expanded into a market town and became a charcoal and leather manufacturing center and brewery.

Opened in 1803, the Surrey Iron Railway from Croydon to Wands worth was the first carriage railroad in the world and later developed into an important mode of transport that prompted Croydon to become London and beyond Commuter town.

By the beginning of the 20th century, Croydon became an important industrial center, famous for its automobile manufacturing, the metal industry and its airport. Into the middle of the 20th century, these industries are the retail industry and the service sector to replace.

Croydon was merged into Greater London in 1965. Traffic is now diverted to pedestrian streets. Its main railway station, East Croydon Station, is a major hub in the British rail transport system and also by Heathrow to Gatwick minicab.

London Heathrow Airport

Often referred to as Heathrow, is the British capital London, a major international airport, and is also British Airways and Virgin Atlantic’s hub the airport, in the Hillingdon area to the west of Greater London.

About 15 miles (24 km) from central London, has two parallel east-west runways and four terminals, one of the busiest airports in the country and in the world. The operating agency is Heathrow Airport Holding Company.

As of 2016, Heathrow Airport’s total passenger traffic ranks the 7th in the world’s airports, but with a large number of cross-boundary flights, it ranks second in the world if only cross-border passenger traffic is calculated. Since 2014 Second only to Dubai International Airport.

Heathrow Airport is also the busiest airport in Europe at the same time, 31.5% more than Paris- Charles de Gaulle Airport and Frankfurt International Airport, yet the number of flights is one-third less than the sum of the two airports

This reflects the fact that due to the limited number of flights, airlines mostly operate routes to Heathrow Airport using widely-laden wide-body passenger planes such as the Airbus A380, Boeing 747 and Boeing 777.
